VEHICLE WINDOW AND VENTILATING SYSTEM Patented May 12, 1942 i UNITED STATES PATENT OFFICE' VEHICLE WINDOW AND VENTILATING SYSTEM Application April 14, 1933, Serial N6. 666,130 8 Claims. (01. 280-44) My invention relates to improvements in ventilating systems for moving vehicles. While my invention is primarily adapted for use in a moving vehicle, such as an automobile, it is obvious it may be employed in any type of a moving vehicle, such as a cabin airplane, bus, railroad car, steamship, cabin yacht, or any closed vehicle that has a forward motion.

The problem of properly ventilating closed in vehicles has been a difficult one for solution. While I am aware that others have provided different types of Windshields, telescoping windows, slidable and pivoted windows, so far as I am aware all the pivoting windows have been pivoted at an end thereof. In the broader aspects of my invention I therefore provide a side window aperture in the vehicle, and a ventilating window pivotally mounted and set-up with. the pivot points thereof spaced from the ends thereof, whereby the rear end of said window or closure may be pivoted outwardly of said vehicle, and locked in an adjustable outwardly pivoted position, in the path of the on-draft caused by movement of the vehicle. With such a construction it is thus obvious that the window is centrally pivoted in an aperture and locked in an oblique angular position with the rear end thereof extending obliquely outwardly laterally of the vehicle and the front end thereof extending obliquely laterally inwardly of the vehicle, thus providing an in-draft in the front end of the larger aperture and an out-draft aperture in the rear end of said larger aperture. As the on-draft hits the inclined rear of said ventilating window, it is obvious it will be split up into two components, namely, a component which is deflected outwardly of said rear end and a component deflected inwardly and through "the front end of said aperture into the vehicle. The inner end of said ventilating window will therefore assist'in defleeting this component forwardly against and along the windshield or front portion of the vehicle, where employed, particularly if my device is attached to the front window orfront portion of the vehicle. There will thus be an in-draft admitted through the open front portion of the aperture and forced around the inside walls of said vehicle, and at the same time the outwardly pivoted rear end of said closure or window pane will cause a vacuum to be formed behind it by the air pressure on the front thereof, thereby tending to suck or draw air out of the rear open portion of said main aperture. It is obvious this will tend to suck or draw air out of the vehicle deflected outwardly by the inwardly projecting open front end thereof, so as to'form a substantially circular continuous passage around'the inside walls of the vehicle, forming an ingress for The enclosure or window pane may be open the desired amount so that merely a slight ventilating draft will be circulated around the inside walls of the vehicle without constantly blowing on any of the occupants, sufficient to cause the desired number of air changes in the vehicle for the proper amount of oxygen within the vehicle and tending to clear the vehicle of all smoke and poisonous carbon monoxide or any other gases which may tend to be formed therein while the vehicle is in use. It is also apparent that when the vehicle is subject to changes in pressure as is often the case in airplanes flying at high altitude that the changes of pressure between the inside and outside 'of the vehicle will be correspondingly less. It is obvious that insomuch as the continuous draft is formed around the wall of the vehicle, that it will not blow directlyon any of the occupants thereof tending to give them colds or otherwise affect their health, but will provide a ventilating draft suflicient to eliminate stuffiness and provide plenty of oxygen, and tend to eliminate the formation of ventilatingmist which often forms on a windshield. a

While my invention may be inserted in any portion of a side wall of a vehicle, a more com 7 plete circuitous circulation is formed if the pivoted closure is attached near the front end of the vehicle, so as to deflect a draft around the inner surface of the front wall and around the inner surfaces of the side and rear walls of the vehicle. In my preferred embodiment, I preferably locate the pivoted closure member above the normal level-of the occupants therein, so' that sufficient circulating draft will be formed without directly blowing on the occupants.

My invention further relates to the features of construction of the specific embodiment shown herein in which the ventilating window is preferably cut from and pivotally mounted as explained on a main window of the vehicle to be slidable therewith to a closed position.

These and such other objects of my invention which may hereinafter appear will be best understood from 'a description of an embodiment thereof, such as is shown in the accompanying drawings;

In the drawings, Fig. 1 is a perspectiveview of v the front 'of an automobile with my invention attached to a usual slidable front window thereof, and with the ventilating window thereof pivoted to an open ventilating position.

Fig. 2 is a perspective View generally similar to.

Fig. 1 with my improved ventilating window pivoted and locked in a closed position flush with the usual slidable front window, whereby as shown, the entire ventilating window and slidable window may be moved out of the way to provide an entirely open windowas-is often desired.

Fig. 3 is a diagrammatic plan view illustrating the substantially circular continuous air current formed in the vehicle around the inside walls thereof by the use of my invention.

Fig. 4 is a side elevation of; the upper front corner of the usual slidable window of a vehicle with my invention attached partially broken away to show parts thereof in section.

Fig. 5 is a cross sectional view looking downwards through an open ventilating window, as

suggested in Fig. 1.

Fig. 6 is a side elevation of the inside of a slidable window having my invention attached thereto, and illustrating in dotted lines a conventional type of window lifting mechanism.

In thedrawings, wherein like characters of reference indicate like parts throughout, I0 generally indicates a vehicle to which my invention may be attached.

While I have shown my invention attached to an automobile, it is obvious that it may be emspaced distance from the ends thereof. In the preferred embodimentshown I do not locate the pivot points substantially at the center of. the

ventilating window, but place them a distance away from the front end thereof.

While I am aware that others have provided pivoted windows'as ventilating mediums for vehicles, so far as I am aware they have been pivoted exactly'at the ends thereof. By spacing the pivot points from the ends thereof, however, I am enabled to provide the complete and novel type of ventilating system about to be described. I also have constructed my invention so that the rear end of the ventilating window may be pivoted outwardly in said vehicle-and locked in pref erably adjustable outward pivoted positions. By pivoting the rear end of the ventilating window outwardly I have been able to obtain novel results in ventilating systems, not hitherto attained and later to be described. While my improved pivoting window I2 may be mounted within any suitable aperture I4 in any portion of the side wall ,of said window I6.

'46 in the lower frame wall 22.

window I6 I preferably pivotally mount it in the front upper corner thereof. This attains not only a decided advantage in operation, but also has the additional structural advantages about to be described. One advantage is that my improved ventilating window I2 may be constructed of an already existing part of the front window I6 by merely cutting it away from the upper front end thereof and mounting it in a suitable frame I8 for this purpose mounted in the upper front end While said frame may be constructed in any suitable fashion, I preferably provide the window frame I8 substantially quadrilateral in form corresponding in size to the cut away aperture. The inner wall 20 thereof, and the lower wall 22 thereof are preferably provided with the outwardly projecting channel forming arms 24 forming the channel 26 in between'them. The frame I8 therefore may be readily mounted on the window I6 by inserting said arms 24 over the adjacent edges of said window I6 adjacent to the rear and lower edges of said aperture and thus the entire frame may be secured to said window edges by means of felt 2B 01' any suitable type of glue securing them there- The frame I8 also has the top wall 34 and front wall 3t, thereby forming a complete four cornered frame. As constructed the top and front walls are constructed of one unit and the rear and lower walls having the channels therein are constructed of another unit, which units may be secured together by means of the screws 38. I then pivotally mount the small window sash 40 on said window frame I8 on vertically aligned pivot points 42 and 44 spaced from the front end of said frame I8 for a purpose to be described. The lower pivot 44 comprises the usual pivot lug 44 registering within a'corresponding aperture In my preferred embodiment I provide spring means 48 to normally close the pivoted pane I2 to a position flush with said slidable pane I5, and for this purpose I provide the enlarged aperture 50 in the top wall 34 of said frame having a smaller innerportion 52 in which the upper end of the pivot lug 42 of said sash may register. A coil spring 48 has its inner end 54 attached to the lower enlarged portion of said pivot 42, extends helically around said lower enlarged portion within the enlarged portion of said aperture and hasthe outer end 56 thereof rigidly attached to said upper frame end 34. It is thus obvious that as said ventilating window I2 is opened that the spring will become contracted and when the window is no longer held open that thespring 48 will then return the window back to a position flush with bodiment this male portion comprises a ball 64 conveniently'attached and mounted on a spring t6 having the inner end thereof normally retained within an aperture 68 in the upper wall of said frame. I also provide means to hold the rear, end of said pivotable pane pivoted outwardly adjustable amounts. While any suitable type of means may be. provided for this purpose I cut away the upper portion of said frame bar as at I6 and provideit below said cut away portion with a guideway I having spaced inwardly extending notches I2 therein. The cutaway portion of said lower frame bar is-adapted to receive the locking bar I4. Said locking bar'ld is pivotally attached as at TI to the lower sash portion 40 and is provided with the locking pin 19 projecting downwardly from the inner end thereof. It is obvious that when the vehicle is in use the pressure'of the draft against the outer end I3 of said pivoted window I2 will tend to force said window inward, but the pin 19 fitting in the notch 12 v will prevent inward movement thereof and hold the rear end I3 of said ventilating window in predetermined adjustable amounts outwardly from said window frame and sash and slidable pane I6. While the sash 48 may consist as shown in Fig. 5, it may have arms 24 projecting inwardly thereof adapted toreceive the window pane I2 therein, and it is obvious that it can be secured thereto by felt 28 or cement or in any suitable fashion. ,In "the embodiment shown the sash does notcontinue along the inner end of the pane, but it may be so continued if desired. It is apparent that when the ventilating pane I2 is swung to a closed position flush with the slidable window II; that the slidable window I may then be lowered into the well of the door clear of the window opening. This may be accomplished by any of the conventional types of window lifter mechanisms, one of which is illustrated in Fig. 6.

While if desired, my improved ventilating pane I2 may be pivoted inwards or outwards, it is primarily adapted to have the rear end I3 thereof pivoted outwards, and in order that it may form a tight fit with the front window pane I6 I preferably provide the weatherstrip 80 on the outside edge of said small window frame in front of said pivots 42 and M and the Weatherstrip 82 on the inner surface thereof in rear of said pivots, so that both ends of the ventilating window may close about the Weatherstripping to form a compact fit when desired to prevent the leakage and moisture from water therein. Any suitable standard type of means (not shown) is provided to move the slidable window from a closed to an open position.

I have shown in Fig. 3 the operation of my improved ventilating window. The ventilating window I2 is pivoted so that the rear end I3 thereof may lie obliquely outwardly of the car and the front end I5 thereof extended obliquely inwardly of the vehicle. While I have in a preferred embodiment of my invention and for the advantages explained above shown my improved ventilating window I2 as being mounted on the usual front slidable window I6 of the vehicle,-so that it may be readily removed out of the way therewith, it is obvious that insofar as the ventilating principles and system of my invention be considered that the ventilating window may be vertically pivoted in any portion of the side walls of the vehicle. In Fig. 3 it is assumed that the rear end of said ventilating window I2 is pivoted outwards and locked in an adjustable pivoted position as shown more particularly in Fig. 5. It is then obvious that the on-draft caused by movement of the vehicle will strike the outer surface of the exposed inclined rear end I3 of said Ventilating window and may be split up into components. One component I! will be directed outwardly from said exposed rear end and the other component [9 will be deflected inwardly through the aperture 2I formed between the pivot points 42 of said ventilating window and the front edge of said main slidable window and said component I9 will supplementally be forwardly deflected against the windshield by the inwardly extending front end I5 of said ventilating window. It is thus obvious that the component I9 will be deflected inwardly against the windshield and will travel in a substantially circular path around the inside walls of the vehicle as shown by the arrows in Fig. 3. It is also apparent that the component I! and other air rushing quickly past the inclined outer rear end l3 of said ventilating window will tend to form a vacuum inside of said window which will tend to draw air from the inside of the vehicle outwards through the aperture'23 then formed between the pivot points 42-64 of said window and the rear edge of said main aperture [4. This vacuum will tend to draw air from the vehicle outwards through the aperture 23 and the component I9 will be aided in its outward passage through the vehicle by striking the inner surface ofthe rear end of said ventilating window. If, however, as shown the ventilating window is located in the upper portion of the usual slidable window, or in the upper portion of the vehicle above the normal level of the occupants therein, it is apparent that a ventilating draft will be formed around the inside walls of the vehicle above the normal height of the occupants therein, as in my specific construction shown. While I preferably locate my improved ventilating window as shown in my preferred embodiment, it is obvious that it may be located in any part of the side walls of the vehicle and that 7 while my invention is primarily adapted for use in automobiles, it is equally adapted for any type of a closed forwardly moving vehicle, the air draft forming features functioning in a similar fashion no matter where located in the side walls of the vehicle or in any type of a closed vehicle.

When it isdesired to completely close the main window IE, it is obvious that the ventilating win- .dow I2 may bereadily pivoted to a closed position in the plane of and flush with the window I6, when the slidable window I6 may be readily moved to a position fully opening the window by the means hitherto described for this purpose.

It is understood'that my invention is not limited to the specific embodiment shown or method described and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
